Authorities are investigating a weekend vandalism rampage that caused extensive damage in Black Hawk County. Windows were shot out of several vehicles throughout Waterloo and Cedar Falls late Friday night or early Saturday morning. Nearly 250 cases were reported in the two cities. Police say damage in Cedar Falls alone is around 70-thousand dollars. Officials believe a small to medium-sized red pick-up truck may have been involved in the rampage. Authorities are looking for whoever’s responsible, but have very few leads to go on.
